Have we been here before?
Déjà vu is a memory problem, Tonegawa explained, occurring when our brains struggle to tell the difference between two extremely similar situations. As people age, Tonegawa said déjà-vu-like confusion happens more often—and it also happens in people suffering from brain diseases like Alzheimer’s. “It’s not surprising,” he said, “when you consider the fact that there’s a loss of or damage to cells in the dentate gyrus.”
Maybe yes, maybe no. Scientists have found the area of the brain responsible for it:
But a new study suggests only a small chunk of it, called the dentate gyrus, is responsible for “episodic” memories — information that allows us to tell similar places and situations apart.

In other Alzheimer's news:

Rachelle Doody of the Baylor College of Medicine in Houston released one-year results for Dimebon, an antihistamine that once was used to treat hay fever in Russia but is no longer on the market. Doody's team treated 183 patients with Dimebon or a placebo for 12 months. The team found that people who took Dimebon improved on several measures of memory and thinking ability at first but showed some decline as time went on. After a year, the patients who took Dimebon still scored better than the placebo group did, Doody says.

Sam Gandy, a spokesman for the Chicago-based Alzheimer's Association, says Dimebon seems to work like existing drugs that treat the symptoms but don't affect the underlying damage caused by the disease.
Well, it's something.
